Cloud Developer

Position Description

This role is hybrid and requires you to be at our Client office at a minimum 4 days per week - subject to change at any time.

We are seeking a hands‑on Cloud Developer to design, build, and operate scalable, secure, and resilient cloud‑native applications and services. You will work across APIs, microservices, event‑driven systems, and data integrations, leveraging modern CI/CD and cloud platform capabilities to deliver high‑quality features at speed.

The ideal candidate has strong software engineering fundamentals, experience with Azure (preferred) / AWS / GCP, and a track record of building production‑grade cloud services. Experience in banking/payments is highly desirable.

• Design and implement cloud‑native microservices and APIs using modern language stacks (e.g., .NET/Java/Node/Python).
• Build event‑driven components using messaging/streaming (e.g., Kafka, Azure Service Bus, Event Hubs, SNS/SQS).
• Implement secure, scalable, and resilient solutions leveraging managed cloud services (compute, storage, networking, identity).
• Write clean, maintainable, testable code with unit/integration tests and clear documentation.

• Develop and deploy services using containers and Kubernetes (AKS/EKS/GKE) or serverless (Azure Functions/Lambda).
• Use Infrastructure as Code (IaC) (Terraform/ARM/Bicep/Cloud Formation) for repeatable, version‑controlled environments.
• Implement observability (logs, metrics, traces) and instrument code for Application Performance Monitoring (App Insights/Cloud Watch/Stackdriver).

• Integrate services into CI/CD pipelines (Azure Dev Ops, Git Hub Actions, Jenkins), enabling automated build, test, security scans, and deployment.
• Practice shift‑left principles: automate quality checks, security policies, and compliance in the pipeline.
• Support blue/green, canary, or ring‑based deployments, and production rollout strategies.

• Implement cloud security best practices: secrets management, identity & access control (Azure AD/Managed Identities), encryption, and network isolation.
• Address threat modeling, secure coding (OWASP), and compliance needs relevant to financial services.

• Work closely with Product, QE, SRE, and Architecture to align on solution design, NFRs, and release readiness.
• Participate in design reviews, code reviews, and post‑incident improvements; contribute to standards and reusable libraries.

• Proficiency in one or more languages: C#/.NET, Java/Spring Boot, Node.js/Type Script, Python.
• Strong experience building RESTful APIs and integrating with relational/No
  
  SQL databases (e.g., Postgre
  
  SQL, SQL Server, Cosmos DB, Dynamo
  
  DB).
• Familiarity with domain‑driven design (DDD), 12‑factor apps, and clean architecture.

• Hands‑on with at least one major cloud:
  Azure (preferred), AWS, or GCP.
• Practical experience with managed services (compute, API gateways, messaging, serverless, object storage, key vaults).
• Understanding of networking fundamentals in cloud (VNet/VPC, private endpoints, ingress/egress, load balancing).

• Docker and Kubernetes fundamentals (deployments, services, configs, autoscaling).
• IaC using Terraform or Bicep/ARM; environment promotion and config‑as‑code.

• CI/CD with Azure Dev Ops/Git Hub Actions; artifact management and release governance.
• Automated testing (unit/integration/contract) and contract testing tools (e.g., Pact).
• Basic performance tuning and cost‑aware design in cloud.

• Understanding of payment processing flows, idempotency, exactly‑once semantics, reconciliation, and settlement.
• Familiarity with payment rails (e.g., SWIFT, ACH, Fedwire, UPI, RTGS) and ISO 20022/message formats.
• Awareness of security, regulatory, and resiliency requirements in financial services (e.g., PCI‑DSS, data residency).

• Event sourcing/CQRS patterns;
  Kafka streams or Azure Event Hubs processing.
• Experience with serverless event‑driven architectures at scale.
• Knowledge of SRE fundamentals (SLIs/SLOs, error…
